I'm having a problem deciding on a course of action to replace my Nikon F401X. I only have a Sigma 70-210 1:4-5.6 lens in the mix.
My dilemma is this: I am considering buying a Fujifilm Finepix HS30EXR with a 30X zoom which is considered a bridge camera. My other option is to buy a Nikon D3100/5100 replacement which would come with a standard 18 - 55VR lens and use the sigma 70 - 210 lens which I already have for telephoto. Will the Sigma lens autofocus on these two Nikons?
The lens barrel says autofocus.At the business end the lens writing says " SIGMA UC ZOOM 70-210 1:4-5.6 MULTI-Coated Lens MADE in JAPAN 52. Back end of lens has 5 small pins protruding around the barrel in one group of 4 pins and a space and then a single pin, 5 pins in total. It has a manual F stop adjustment at the trailing edge of the lens. There appears to be a serial number which reads 2017941. The lens is quite heavy if that helps.
Now I imagine that the purist will have difficulty understanding why I would even consider a Fujifilm camera but these have improved greatly over the years and work very well. My interests are in landscapes and scenery with some macro and people pictures. For about the same money, both of these options are attainable. Can you help me to value pro and cons of these alternatives?
